Weapons, ships, and many other things.

The Atlantean Spear class ship

A mighty ship some have called it sometimes able to take on a whole fleet and win. Plus due to its nature, it is quite a strange one as well. Mainly to do with the ship creator. The Traveler himself.

Depending on what empire he is in, in what universe, technology level, etc. The weapons, shields, reactor, hull, height, weight, etc can be vastly differently. However, there is somethings that change very little to not at all. Main ones being how many of what weapon type are used. For most of the ships made of this class, they tend to have around 5 to 12 railgun or other physical ammo type weaponry on the ship. The ones he mainly uses are an anti-shield type of railguns or the like. Which is quite standard in militaries with their space ships, more so when most of their foes use shields more than armor. 

Then there is the 12 to 25 energy base weaponry like lasers and lances, etc. Which are mainly used to melt through armor which again. Is quite a normal standard in militaries against ship armor. But of course, one of this energy base weapons on the ship can be a superweapon which like any other superweapon are very costly in minerals and energy but can wipe out a battlecruiser or as far as a planet in one shot. Depending on what it's main use is and the main foes of The Traveler when it comes to his ship.

And now the third type of weaponry on these ships of this class are fighter and or bomber type strike craft. Which are either physical weaponry base or energy weaponry base depending on what is more useful for one thing. Though they may seem like a small part of any military, but in most cases, they can either win or lose a battle if not a war. In wars against a foe that uses only cruisers and up kind of classes, will have a hard time dealing with strike craft unless they put quite a few anti-strike craft guns on their ships which in most cases will limit the number of other guns and or shields that can be on their ships. Due to the small but very quick nature of strike craft. Mainly the bombers which the main job of them is to take out cruisers, battlecruisers, etc. Since most of those ships will be focus only on taking out others of their class, making them weak to strike craft unless they carry strike craft of their own and or if there are corvettes, frigates, etc. With the other ships to mainly fight against their own ship class and sometimes strike craft.

Of course one last important detail about this ship. Is that it has psionic batteries within itself to store psionic energy for later use. Mainly for the shields, but can also be used for its warp drive or hyperdrive, or whatever drive it has. Along with the sub-light engines, weaponry. and a few minor parts of the ship like heating, lights, etc. Though only in theory, it is possible that psionic energy could be used to effect the hull of the ship but this is untested and not sound since metal can react in countless ways base on shape, height, weight, etc. Which would make sense if The Traveler does know how to do this sort of thing given his "immortal" life, and other details about him.

This ship class is almost always a flagship of whatever empire he is in. Why this is the case is not sure. Most likely to deal with being limited in psionicly powerful beings that could help him when in battle, which is a topic for another time.
